Therefore, when the operating surface is pushed in, the operating member 12 moves in the pushing direction (rear), and the retaining plate 15 that moves in the pushing direction together with the operating member 12 presses the working surface 33 of the elastic member 16 backward. It deforms to bend. Then, the rear surface of the deformed working surface 33 comes into contact with the switch 50, and the switch 50 is finally operated. When the pushing operation is released, the operating member 12 and the retaining plate 15 return to the position before the pushing operation by the urging force of the coil spring 13, and the elastic member 16 returns to the state before the deformation by its own elastic force. Return.

According to the intercom slave unit 1 provided with the emergency button device 11 as described above, the operation member 12 is provided with an operation protrusion 21 that projects rearward from the rear surface side of the operation surface and has a smaller front view than the operation surface. On the other hand, the front button case 14 is screwed to the rear surface side of the front case 2 so that the insertion cylinder 25 and the wall portion 26 penetrate through the mounting opening 7 from the rear side to the front side to form the front surface of the main body case. As a result, a button opening (the tip opening of the insertion cylinder 25) is opened on the front surface of the main body case so that the operation protrusion 21 can be inserted and the front view is smaller than the operation surface. Further, a retaining plate 15 is provided on the inside of the main body case (on the inner surface side of the front case 2) so that the front view is larger than the button opening and is integrated with the tip of the operation protrusion 21. Therefore, even if the emergency button device 11 having a large operation surface is provided, the operation member 12 can be suitably attached even if only a button opening smaller than the operation surface of the operation member 12 is opened, so that the operation member 12 is waterproof. It is possible to prevent the decrease.

Further, an elastic member 16 is provided between the retaining plate 15 and the switch 50 of the emergency button device 11. Then, the elastic member 16 is deformed by being pressed by the retaining plate 15 due to the movement of the operating protrusion 21 and the retaining plate 15 in the pushing direction accompanying the pushing operation of the operating surface of the operating member 12, and the deformed elastic member 16 causes the elastic member 16 to be deformed. The switch 50 is operated. Therefore, it is possible to easily realize a structure in which the switch 50 is reliably operated by the pushing operation, and the switch 50 is less likely to be damaged.

Further, the front surface of the main body case is composed of a front case 2 and a front button case 14 fixed to the front case 2 and having an open rear surface, and protrudes rearward toward the inner surface side of the front button case 14. The holding cylinder 28 is provided, the retaining plate 15 is provided in the holding cylinder 28, and the elastic member 16 formed into a disk shape having substantially the same diameter as the holding cylinder 28 in front view is the holding cylinder 28.
